Flowers for Friday

The vegetation at school and throughout Chiangmai is lush and green and colourful.
I'm enjoying the floral displays, not that I know what many of the flowers are.
 These are some flowers I found growing in the surrounds of a temple in Chiangmai. The cannas and the frangipani are familiar. The red flower in the middle grows everywhere and is called the needle flower and I don't know what the white one is.  Friday flowers for you!!
